There are 2 rows and 4 columns, so it's a 2x4 matrix

if you have m rows and n columns, then you will have an   m x n   matrix

Well, you covered the cola solution... RC, Rows by Columns.  But here is the original in $\LaTeX$.  Right click the code and go to Show math As $\rightarrow$TeX Commands if you want to know what I put between $\backslash$[ and ]\ to get that.
$$\left[
\begin{matrix}9 & 1& -2& 8\
0& -3& 1& 4
\end{matrix}
\right]$$
